Music mavens head to this “out-of-the-way” Potrero Hill haunt to “rock out” to the “top bands of tomorrow” in an “intimate”, “dark” and “divey” atmosphere; it can feel like a “madhouse” with “ear-piercing” noise, but at least there’s the “back patio for relaxing between sets”, plus plenty of “cheap” drinks served up by an “attentive” staff.
